Forget the Porsche — guys who really want to attract women should be driving a Prius.

Sexy models draped over sports cars at the New York Auto Show aside, most women prefer a man who drives something more practical, according to a new survey.

A Harris poll commissioned by dating site AnastasiaDate found that a majority of women associate fancy cars with negative character traits: 56 percent view men who drive exotic or fast cars as being showoffs or arrogant, and 17 percent perceive them as being insecure.

Almost half of women say that a guy’s car reflects his economic status. Forty-six percent say that it reflects a guy’s image of himself. Eleven percent believe that the car reflects the guy’s feelings about having a family.

Only about one-fifth of women say that they have found a man more attractive after seeing the type of car that he drives.

And 37 percent of women think men who buy expensive cars are compensating for a lack of “something.”

Men have their own opinions about what a woman’s ride says about her.

Nearly 40 percent of men think a woman in a fast or exotic car is a showoff. Six percent see those women as emotional.
